Application filed June 6,

To all to ham it may concern.

lie it known that l, Enwn G. Brissn, a citizen of the Un'ted States, residing at Chlcago, Illinois, have invented a certaln new and GS tul Improvement in Brake-Beani- Hanger-Locking Keys, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part or" this specification, in which igure 1 is a side elevational view of my improved brake head.

Fig. 2 is a front elevational view of a brake head provided with center rib, to which-my invention is applied.

ll 8 is a front elevational view of a brake head with outside ribs, to which my invention is applied, the same being illustrated as cooperating with the center rib.

T his invention relates to a new and useful improvement in looking keys for brake beam hangers, the object being to prevent the brake hanger from contacting with the key which locks the brake shoe to the head, and hence unnecessary wear is avoided.

My improved brake beam head is provided with openings equidistantly spaced and into which hre adapted to be inserted the legs of a ll-shaped locking key to prevent the acci dental displacement of a hanger when enga ed in the upper or medial opening of the The cross bar of this safety brake head. lock is ofifset slightly from the plane of the legs so that its relation to the hanger is to one sid '2". 6., that side which in effect closes the ham opening in the brake head. The legs of the locking key may be sprung or bent so that the key is locked in position when inserted. to close the front opening of the brake beam hanger and by providing the cquidi. ant openings, the same key may be employed for upper hanger opening or a medizl hanger opening, as desirer. Hence, it from severe service, the brake shoe is worn down to such an extent that the usual key is lost, the brake hanger key lock mounted in the brake head will maintain its position and hold the brake hanger to its seat,

n Fig. l the brake shoe is shown as hava rake hanger arranged in the upper n'ng, said brake head having openings o which the legs of a ll-shaped locking are fitted. The cross bar of this lockj key is offset from the plane of the legs i will lie in front of the recesses or openings provided in the bralrc head to receive the brake hanger. These legs may either be bent or prung before insertion so that they will hold themselves in position, or they may be bent after insertion so that the hanger loch will be permanently secured in position, as shown in Fig. 2.

shown in Fig. 0, the lock may be used to close the medial opening it the brake hanger is employed at that point.
